I'm 37, prob one of the oldest in here.
I say it's definitely worth it, look at all these people who live boring ass lives, same old shit day in day out. 99% of those my age have given up, depressed, on anti anxiety Meds, FAT, out of shape, on and on.
I cycle so it's fun, I look forward and plan cycles, get my stuff and feel like a little kid at Christmas when I see a FedEx package! I have goals and makes me train hard and eat right, I have a ton of energy and look amazing. I feel like I'm driving a Lamborghini and everyone else is stuck in 1st gear in a Honda Civic
I think the key is moderation, I kept doses under a gram, and do 2 cycles a year, about 12-14 weeks each so it adds up to the old school time off=time on. Stick to safe compounds like test, deca, var. try to eat healthy and train when off and you'd be surprise how much gains you can kept.
I had kids a while back and was off a year, shrunk to 216. Cycles back up to 245, and now been off 6 weeks and still around 233-235...
I love it. Just don't abuse it. If ur not competitive I'd stay the hell away from insulin or diuretics and never do rec drugs
